What does this mean?Pros & Cons
Pros
This keypad switch works with raspberry pi. On tap for my husband's upcoming robotics project.
Highlights
Quality
This panel seems robust and well designed.
I just tested the contact resistance andit seems with in specs, i measuring anywhere between 29 and 50 ohms, with a nice solidconnection.
After removing the film on the back, in order to use the adhesive, the wiring becomes visible.
The pad itself is very thin and flimsy, that’s not a bad thing, but needs to mounted’ to something flat.

I would like the contact resistance be higher

I checked the values with a multimeter and they varied between 400 and 700 ohms

This is perhaps okay but i will be adding four resistors in series with either the horizontal or the vertical lines to ensure no real current

The 8 lines are divided along the middle with four lines going vertically and four horizontally

After attaching it on a surface i had to peel it off once before replacing it and that put some heavy strain on the panel and i was sure it wouldnt work afterwards being so severely bent while pulled off but it worked fine with nice click feel of the buttons

I havent written code for scanning this yet but that should be easy enough cycling over four lines the vertical or horizontal group designated as output setting one high at a time then scanning the other four set as inputs
